errors are handled (these gave ``TypeError: not enough arguments'').
Also changed its __str__() to correct a typo (missing self.) and
return str(self.msg) to ensure the result is always string.
Also changed the default __str__ to simply return str(self.args).
This doesn't yet support "import a.b.c" or "from a.b.c import x", but
it does recognize directories. When importing a directory, it
initializes __path__ to a list containing the directory name, and
loads the __init__ module if found.
The (internal) find_module() and load_module() functions are
restructured so that they both also handle built-in and frozen modules
and Mac resources (and directories of course). The imp module's
find_module() and (new) load_module() also have this functionality.
Moreover, imp unconditionally defines constants for all module types,
and has two more new functions: find_module_in_package() and
find_module_in_directory().
There's also a new API function, PyImport_ImportModuleEx(), which
takes all four __import__ arguments (name, globals, locals, fromlist).
The last three may be NULL. This is currently the same as
PyImport_ImportModule() but in the future it will be able to do
relative dotted-path imports.
Other changes:
- bltinmodule.c: in __import__, call PyImport_ImportModuleEx().
- ceval.c: always pass the fromlist to __import__, even if it is a C
function, so PyImport_ImportModuleEx() is useful.
- getmtime.c: the function has a second argument, the FILE*, on which
it applies fstat(). According to Sjoerd this is much faster. The
first (pathname) argument is ignored, but remains for backward
compatibility (so the Mac version still works without changes).
By cleverly combining the new imp functionality, the full support for
dotted names in Python (mini.py, not checked in) is now about 7K,
lavishly commented (vs. 14K for ni plus 11K for ihooks, also lavishly
commented).
Good night!
is like PyImport_ImporModule(name) but receives the globals and locals
dict and the fromlist arguments as well. (The name is a char*; the
others are PyObject*s).
Added 'p' format character for Pascal string (i.e. leading length
byte). This uses the count prefix line 's' does, except that the
count includes the length byte; i.e. '10p' takes 10 bytes packed but
has space for a length byte and 9 data bytes.
1. Fix bug in (de)compression objects. The final string resize used
zst.total_out to determine the length of the string, but the
(de)compression object will output data a little bit at a time, which
means total_out is not the string size. Fix: save original value of
total_out at the start of the call.
2. Be sure to Py_DECREF the result value if you exit with an
exception.
3. Use PyInt_FromLong instead of Py_BuildValue
4. include more constants from the zlib header file
5. Use PyErr_Format instead of using a local buffer and sprintf.
(though some type names are undefined in that case, e.g. CodeType
(inaccessible), FileType (not always accessible), and TracebackType
and FrameType (inaccessible).
Sjoerd: add separate administration of temporary files created y
URLopener.retrieve() so cleanup can properly remove them. The old
code removed everything in tempcache which was a bad idea if the user
had passed a non-temp file into it. (I added a line to delete the
tempcache in cleanup() -- it still seems to make sense.)
Jack: in basejoin(), interpret relative paths starting in "../". This
is necessary if the server uses symbolic links.
- use the DLL versions of the C runtime (!)
- change path settings so intermediate files go to Debug/temp or Release/temp
- add resource file to python15.dll (can't remember what this does)
- add a separate project to build the parser module
dealloc() functions contained code to free/DECREF the buffer
(there were differences between I and O objects but the logic bug was
the same). Fixed this be setting the buffer pointer to NULL and
testing for that. (This also makes it safe to call close() more than
once.)
XXX Worry: what if you try to read() or write() once the thing is
closed?
- Changed semantics for initialized flag (again); forget the ref
counting, forget the fatal errors -- redundant calls to
Py_Initialize() or Py_Finalize() calls are simply ignored.
- Automatically import site.py on initialization, unless a flag is set
not to do this by main().
Added PyErr_MemoryErrorInst to hold the pre-instantiated instance when
using class based exceptions.
Simplified the creation of all built-in exceptions, both class based
and string based. Actually, for class based exceptions, the string
ones are still created just in case there's a problem creating the
class based ones (so you still get *some* exception handling!). Now
the init and fini functions run through a list of structure elements,
creating the strings (and optionally classes) for every entry.
initerrors(): the new base class exceptions StandardError,
LookupError, and NumberError are initialized when using string
exceptions, to tuples containing the list of derived string
exceptions. This GvR trick enables forward compatibility! One bit of
nastiness is that the C code has to know the inheritance tree embodied
in exceptions.py.
Added the two phase init and fini functions.
